Tim,
Named buffers represent convenient and easy to use way how to handle multiple
xml or xslt files. Let me to give you a simple example, which should make it
clear.
use strict;
use XML::Sablotron qw (:all);
undef $/;
# Open and read (or generate) as much files as you wish.
open(FH,"<xslt_template_01.xsl");
my $template1 = <FH>;
close FH;
open(FH,"<xslt_template_02.xsl");
my $template2 = <FH>;
close FH;
open(FH,"<xml_data_01.xml");
my $data1 = <FH>;
close FH;
open(FH,"<xml_data_02.xml");
my $data2 = <FH>;
close FH;
...
# Create a new Sablot object and feed it with data.
my $sab = new XML::Sablotron();
$sab->RunProcessor("$template1", "$data1", 'arg:/result',
[], ['templ2', $template2, 'data2', $data2, ...]);
# You provide this method with the following parameters:
# template, data, name of result buffer, [parameters (none in this case)],
# [additional named buffers (2 in this case)]
# Run the transformation. Other documents can be referenced this way from
# xslt_template_01.xsl: select="document('arg:/data2')/root/child" or
# <xsl:include href="arg:/templ2"/>, for example.
my $result = $sab->GetResultArg('result');

I hope this help.
